3.1. USBXpress Driver Development Kit
The Silicon Laboratories USBXpress
CP210x devices. No USB protocol or host device driver expertise is required. Instead, a simple, high-level Application
Program Interface (API) for the host software is used to provide complete USB connectivity. The USBXpress
Development Kit includes Windows device drivers, Windows device driver installer, host interface function library
(host API) provided in the form of a Windows Dynamic Link Library (DLL). See Application Note AN169, "USBXpress
Programmer's Guide" for detailed information on using the USBXpress drivers.
The USBXpress drivers are available here: www.silabs.com/usbxpress.
Click the USBXpress Development Kit link in the Download for Windows 2000/XP/Server 2003/Vista/Win7 section
to download the USBXpress drivers. Run the installer and follow the steps to install the software to the desired

  • Page 3 5. CP2104 Software Interface If the Virtual COM Port drivers are used, the CP2104 will appear as a COM port in the Device Manager, as shown in Figure 2. The CP2104 will always use the lowest available COM port for operation. For instance, if COM ports 1 and 2 are in use by other peripherals and applications, the CP2104 will use COM 3.
